Application February 19, 1928, Serial No. 341M":

24 Claims. (o1. 274-10) This invention relates to phonographs, and moreparticularly to automatic or self-operating phonographs.

The present application, together with my copending applications SerialNumbers 341,076, now

Patent No. 1,983,087, granted Dec. 4, 1934, and 341,078, now Patent No.1,954,246, granted April 10, 1934, filed concurrently herewith, disclosean automatic phonograph designed with a view to simplifying andaccelerating the record changing operation. In accordance with myinvention, the used record is discharged from the record turntable whilethe table is tilted from the horizontal to a substantially verticalposition, and the next record to be played is picked up by the centeringpin of the table on its upward oscillation back to the horizontal orplaying position. The present application relates more particularly tothe arrangement of the tiltable turntable and the tilting mechanismtherefor, and also to the automatic and manual control means foractuating this mechanism;

One object of my invention is to overcome the dimculty presented by thefact that the turntable must be made tiltable althoughgeared to adriving motor. This I overcome by tilting the table and the motor as anintegral unit, without disturbing the gearing therebetween. Theturntable, the motor, and the tilting mechanism are 30 carried one.frame supported by trunnions, and,

in accordance with my invention, the mass of the table, motor, andmechanism is so distributed that the entire unit is balanced about theaxis of support. 35 A further object of my invention is to providetilting mechanism without necessitating the use of a separate drivingmotor, and to this end I mount a crank on the tiltable frame and anchoror connect it by a connecting rod to a wrist pin 40 fixed in astationary chassis. In this manner the crank may readily be geared tothe motor which drives the turntable, and the resulting rotation of thecrank about its anchored crank pin causes the crank shaft, and thetiltable frame which car- 45 ries it, to move relative to the stationarychassis.

One time saving feature of my invention is' ,that the record picked upby the turntable is moved directly into contact with the reproducerneedle when the table is oscillated toits playing 50 position, andanother is that the tilting operation is made quite rapid in order tospeed up the record changing operation. However, it is necessary that atthe moment of: contact of the record with the reproducer needle theirrelative motion be slow, and to meet this condition is another object ofmy invention, which I do by arranging the crank and connecting rod sothat the crank moves into dead center at the time of contact of therecord and reproducer, thereby bringing them into engagement gently.

The tilting crank is to be geared tothe motor only during the tiltingoperation, and I therefore interpose between the driving motor and. thecrank a single revolution clutch. To prevent over-travel the clutch isdisengaged slightly before the end of a full revolution of the crank. Toinsure the completion of a full revolution, in spite of this necessarilypremature disengagement, is still another object of my invention, forwhich purpose I provide'a cam rotating with the crank, and a camfollower which is resiliently pressed against the cam, the cam shapebeing. such that the pressure of the follower forces it to complete afull revolution, so that the record fiirntable is brought into properplaying posi- Obviously, the turntable should be kept quite rigidly inposition during the playing of records,

and to lock the frame in position is a further object of my invention,which I fulfill by two expedients. The first is the cam to which I havealready adverted, for the cam follower engages a recess in its surfaceand holds it in position. The second consists in so arranging the crankon the tiltable frame, and the connecting rod between the crank and thefixed wrist pin, that the axes of the crank, the crank pin, and thewrist pin are aligned when the frame is in normal reproducing position.

A used record is discharged by tilting the frame to a nearly verticalposition and pushing the record away from the table in order to dislodgeit from the centering pin to permit a gravity drop. The next record tobe played is picked up by inclining it in such a position that itscenter hole lies in the path of the centering pin when the table isbeing restored to normal playing position. The first operation iscertain, and the table may be tilted downwardly quickly, whereas thesecond operation is more exacting and apt to go wrong if made too fast.Also, the used record may be disengaged from the reproducer quickly,whereas the new record must be brought into contact gently. To make thetotal record changing time a minimum by meeting these variedrequirements, that is, to make the downward tilt of the table morerapidthan the restoring oscillation, is a still furtherobject of myinvention. For this purpose the linkage made upof the stationarychassis, the tiltable frame, the crank, and the connecting rod, are soarranged that the frame is given its full downward tilt in about onequarter of a revolution of the-crank, while it is restored to thehorizontal position during the remainder of the revolution of the crank.

When the last of a stack of records has been played, or if only a singlerecord is played at a time, it is desirable to stop the driving motorwhen there is no new record on the turntable, and to provide for this isa further object of my inven-' tion. This I do, by meansof a member,preferably a roller urged toward the peripheries of the record and thetable, and means responsi e to a movement of the roller entirely to theperiphery of the table for stopping the motor. The roller tends to moveinward when the table is tilted, but at this time the motor should notbe stopped because that would interfere with the completion of thetilting operation, and in accordance with a further feature of myinvention the stopping means already mentioned are made inoperative whenthe table is in tilted position. The driving motor is preferably anelectric motor, and the stopping means is simply a switch in series withthe motor. Another switch is connected electrically in parallel with thefirst mentioned switch, and is arranged to be opened when the table isin horizontal position, but is closed when the table is tilted, toprevent opening of the motor circuit.

Any usual type of automatic stop means may be employed in cooperationwith the reproduoer in order to ascertain the ending of the record, andthis means is made to actuate the single revoliition clutch on thetilting crank, thereby disengaging the record and reproducer, andejecting the used record from, the turntable. It sometimes happens thata record, when played, proves undesirable, and a further object of myinvention is to permit of rejection of records at will, to do which Iprovide manually operable means for tripping the single revolutionclutch.

My invention is described more in detail in the following specification,which is accompanied by drawings, in which:

Fig. 1 is a partially sectioned elevation showing schematically thegeneral arrangement of the phonograph;

Fig. 2 is an elevation of the tilting mechanism and turntable in normalplaying position;

Fig. -3 is an elevation of the tilting mechanism and turntable whenfully tilted;

Fig. 4 is a front elevation;

Fig. 5 is a detailed section through the single revolution clutch, takenon the line 5--5 in Fig. 2; and

Fig. 6 is a wiring diagram for the phonograph.

Referring to Fig. 1, there is a record turntable 2 supported on a shaft4, rotated in a tiltable frame, not shown, by' a driving motor 6, whichis geared to the shaft 4 by a worm 8 meshing with a worm wheel 10. Theassemblage is tiltable about trunnions 12 fitted in bearings 14supported on pedestals 16. The reproducer 18 is supported on an arm 20which reciprocates about a vertical shaft 22 fitted within a stationarysleeve 24. The record is separated from the reproducer when theturntable 2 is tilted downwardly. Meanwhile a cam 26 and follower 28 arearranged to reciprocate the reproducer 18 outwardly while the table 2 isbeing tilted downwardly to the position indicated at 2'. At the sametime ejector arms 30 are moved to dislodge a record from the centeringpin, and drop it by gravity into a discard magazine 32. The next recordto be played is separated from a stack of records in the magazine 34 bymeans including a separatingfinger 36, which slides the forwardmostrecord upwardly over edge 37 out of the magazine and onto sup- .port 38.The upper portion of the record leans will be seen that the tiltableframe 40, supported on trunnions 12, carries not only the turntable 2,the turntable shaft 4, and the driving motor 6, but also a crank disk42, the crank pin of which, indicated generally at 60, is connected toone end of an anchor or connecting rod 44, the other end of which isconnected to a wrist pin 46 fixed to the stationary chasis 50.

Aworm 52 on the shaft 4 meshes with a worm wheel 54, which positivelydrives a clutch 'wheel 56, provided with holes 58 in one of which aclutch pin, carried in a single revolution clutch mechanism indicatedgenerally at 60, is inserted to tilt the frame 40. The crank disk 42also acts as a cam, it being indicated at 62 to mark the crank positioncorresponding to the normal playing position of the frame, while afollower 64 is forcibly pressed against the cam by a torsional spring66'. The cam shape is designed to insure completion of a full revolutionof the crank, even though the single revolution clutch is necessarilyreleased a little before the end of a full revolution, and also to helphold the turntable in its normal playing position.

The table is also looked in position by the alignment of the crankshaft, the crank pin assembly 60, and the wrist pin 46. These are indead center, so that any tendency of the table to tilt, in eitherdirection, merely puts the parts in tension or in compression, ratherthan turns the crank.

Fig. 3 is an elevation similar to that shown in Fig. 2, except that theframe 40 has been tilted until the turntable 2 is in a substantiallyvertical position. It is important to notice, in this figure, that thecrank disk 42 has rotated, relative to the frame 40, only about aquarter of a revolution, resulting in a very rapid downward tilt of thetable. To better illustrate this the position of the crank pin andclutch mechanism 60, or of the cam indentation 62, may be compared withsome fixed point on the frame, such as the worm 52, or the cam follower64, and it is evident that these points have moved relatively only aquarter of a revolution, even though the absolute rotation of the crank,relative to the fixed chassis 50, is a half revolution. The remainingthree quarters of the relative revolution of the crank are used inrestoring the turntable to normal playing position, a slower motionbeing desirable when picking up the next record to be played.

Fig. 5 is an enlarged section taken on the line 5--5 in Fig. 2, andillustrates the positively driven clutch wheel 56 formed integrally withthe worm gear 54, and provided with tapered clutch holes 58. Coaxiallymounted with the positively driven clutch wheel 56 is the loose wheel42, which serves not only as the driven member of the clutch, but alsoas a crank disk and as a cam. This wheel carries a crank pin 70, towhich one end of the connecting rod 44'is connected by a bearing 72. Thecrank pin '70 is hollow and carries a clutch pin 74, which isreciprocable within the crank pin 70, but which is splined thereto toprevent 1 relative rotation by means of a key slot 76, engaged by a setscrew 78. There is a plunger 80,

supported in the' stationary chassis, actuation of v which forces theclutch pin 74 into one of the holes 58 in the rotating clutch wheel 56,and so causes the crank to rotate. V 1' 1.

The connecting rod bearing 72 has an enlarged face 82, on which a cam 84is fixed. The end of the reciprocable clutch pin '74 carries a camfollower 88. The cam and follower experience relative rotation becauseof the eifectof the key 78,

and near the end of a single revolution the follower 88 rides up on thecam surface 84 and retracts the clutch pin '74 from engagement with thepositively driven clutch wheel 56. The holes 58 and pin 70 are slightlytapered to permit ready retraction. The outer end of the clutch pin 74carries a curved shield 90 to prevent jamming of the clutch pin againstthe plunger 80, should the latter through some mishap not have beenrestored to its normal position.

This single revolution clutch is particularly advantageous because it isan arrangement in which the relative revolution is obtained withoutreference to a fixed point located on the stationary chassis. It will beunderstood that the retracting cam may be of any type, and particularly,the cam surface may be attached 'to the clutch pin 72, while theconnectingrod bearing face 82 may be made to act as a cam follower. I

The general assemblage is illustrated in the front elevation, Fig. 4,which shows how the clutch pin 74 is aligned with an actuating plunger80, in this case magnetically operated by the at traction of a magnet92, attached to the stationary chassis 50, on an armature 94, fixed tothe plunger 80. This figure also shows how the tiltable frame 40,carrying the turntable 2, the turntable shaft 4, the driving motor 6,and the crank and clutch mechanism, is supported by trunnions 12 mountedin pedestal bearings 14.

A wiring diagram for the phonograph is given in Fig. 6. Energy from asupply line 100 is fed to the driving motor 6 whenever the circuit isclosed by either a manual switch 102, or either of the automaticswitches 104 and 106, these switches all being connected electrically inparallel. Switch 106 is arranged, as shown, to be opened when theturntable is in normal playing position, but closed when the table iseven slightly tilted. The switch 104 is operated by a roller 107,supported on an arm 108, which is pivoted at 110 to the stationarychassis, and urged toward the periphery of the record truntable 2 by atorsional spring 112. The turntable is smaller in diameter than therecords, and the screw 114 is so adjusted that the contact 104 is openedwhen the roller 107 moves entirely over to the periphery of theturntable 2, without being stopped by a record. A roller or other wipermoving normally'of the table, and depending for actuation upon thepressure of the record, might equally well be used, but I prefer thepresent scheme because the roller is also used to switch 106 keeps thecircuit closed until the tilt,-

ing cycle has been completed.

Some of the energy from the line 100 is supplied through a transformer120 to a magnet 92, which is arranged to attract the armature 94 inorder to move the plunger 80 against the clutch pin 74. The magnetcircuit is closed by a contact 122 which, when the reproducer armreaches the end of a record, is actuated in any conventional manner, andthus trips the single revolution clutch and ejects the used record. Amanually operable switch 124 is arranged in parallel with the automaticswitch 122, so that a record and thereby repeating the tilting cycle.

may be rejected at will, without waiting for its completion.

To start the machine the button 126'is' depressed, which closes theswitches 102 and 124. The closing of the switch 124 trips the singlerevolution clutch, while the closing of the switch 102 starts thedriving motor 6, so that the turntable 2 immediately begins to tilt. Thebutton must be depressed long enough for the table to begin to tilt,whereupon the contact 106 is closed, and remains so until the tiltingcycle is completed. When the table is restored to its operatingposition, it carries a record which moves the roller 107 outwardly,which closes the contact 104 so that the driving motor continues tooperate. At the end of the record the contact 122 is closed, trippingthe single revolution clutch, If no record is brought up with the tablethe motor circuit is opened by the wheel 107 opening the contact 104. Ifa record already begun is considered undesirable, the button 126 maybedepressed, tripping the single revolution clutch and ejecting theundesired record.

It may incidentally be mentioned that the reproducer 18 is preferably ofthe electrical type, and its pick-up is led over conductors 130 to asuitable amplifier, which, in the case of a combined radio receiver andphonograph, may be the amplifier of the radio set.
